Plan the next stage of your facility’s power. Bring a defined hardware combination to your expansion study: an original Cummins 6ZTAA13-G3 diesel engine, original Stamford HCI444FS1 alternator and original Deep Sea Electronics DSE7320 controller. Explore the 300kW class with the load information, operating priorities and connection requirements that matter at your site.
The offer should state its duty rating and electrical output under the agreed site conditions. The power-class label alone does not complete the selection.

Begin with the demand
Separate the whole building from the loads you intend to supply.
An expansion may add a new process, a larger production area or a different mix of equipment. Define which circuits belong on generator power before using the facility total as a sizing target.
For a replacement project, retain the old generator’s operating records as background. Reassess the actual load rather than assuming that the previous nameplate describes today’s requirement.
A
Essential demand
Identify the equipment that must remain available during the intended operating period. Record its normal demand and the conditions that cause it to increase.
B
Deferrable demand
Mark processes that can wait or be excluded from generator operation. State who makes that decision and whether the separation is achieved electrically or through an operating procedure.
C
Planned additions
List future machinery separately, including the information already known about it. Distinguish confirmed additions from an early estimate so the review can track its assumptions.
Look beyond the running total
Put changing demand into the sizing review.
Two facilities with similar running demand can present different starting and load-change requirements. The technical assessment should examine the equipment behaviour behind the total.
MOTORS & DRIVEN EQUIPMENT
Describe the start, not just the nameplate.
Supply motor data and the proposed starting method. Identify machinery that may restart while other loads remain connected, together with any restrictions on its starting sequence.
ELECTRONIC & VARIABLE LOADS
Identify the electrical characteristics.
Flag drives, UPS systems and other electronic equipment in the load list. Provide the available input data and ask the electrical designer to consider their effect on alternator selection and supply quality.
CYCLING & COINCIDENT DEMAND
Show which events can overlap.
Describe equipment that switches automatically or changes demand during a process. Highlight combinations that could occur together so the assessment is based on a realistic operating case.
Use records with context.
Attach measured demand profiles where available. Note the season, operating shifts and equipment included in the readings; add starting information and planned changes that the measurements do not capture.
Fit the unit into the facility
Review the interfaces before committing to the installation.
A larger power class changes the discussion beyond the generator itself. Bring the existing electrical arrangement and site conditions into the same review as the proposed unit.
Distribution and changeover
Provide the single-line diagram and details of retained switchgear, cables and changeover equipment. Have the responsible electrical designer review the proposed connection, protection arrangements and equipment ratings.
Environment and enclosure
State the site elevation, ambient conditions and installation location. Request the applicable output basis and enclosure arrangement for that environment, with the supporting technical data identified in the offer.
Building and service routes
Supply the available space and the proposed routes for ventilation, exhaust and fuel services. Obtain arrangement drawings before checking access, maintenance clearances and the installation work to be performed locally.
Supervision and responsibilities
Describe the required local indications, external signals and remote supervision. Ask for the DSE7320-based arrangement and any additional interfaces to be listed so the controls scope can be reviewed explicitly.
Send enough context to connect the generator proposal with the facility’s next operating stage. Keep uncertain items visible so they can be resolved during selection.
Explain when the unit will run, the required supply arrangement and which processes it is intended to support.
Load evidence
Include the prioritised load list, available demand records, motor starting data and planned additions.
Site information
Provide location conditions, space constraints and drawings of the proposed installation interfaces.
Selection criteria
State the electrical characteristics and project acceptance criteria that the proposed configuration must address.
Selection questions
Resolve the assumptions behind a 300kW request.
These questions help the project team prepare the information needed for a capacity review and a clearly defined offer.
Does a 300kW label establish how much of our facility can run?
The load study determines that. Share the circuits you intend to energise, their expected demand and their starting characteristics. The proposed unit needs to be assessed against that combination, the requested duty and the installation conditions before its usable capacity is accepted for the project.
How do we present equipment that has not been installed yet?
Identify proposed equipment separately from the operating plant. Include the available manufacturer data, expected installation date and whether it must run during generator operation. This lets the reviewer distinguish a committed expansion from an allowance that may change.
What if our measurements cover only a quiet production period?
Describe when the readings were taken and which processes were active. Add the missing peak-period information when available, together with equipment starting data. A low-demand snapshot should be labelled as such so it is not mistaken for the complete operating profile.
Can a retained ATS or distribution board be part of the enquiry?
Yes. Supply the existing equipment identification, ratings, drawings and proposed connection arrangement. Ask the project engineer to assess its suitability alongside the new generator. Identify any required replacement, protection review or control changes in the integration scope.
Should an unverified future load be included as a fixed requirement?
Record the assumption and the information still needed to confirm it. Ask for the selection to be revisited once the load details are available. An unexplained percentage reserve does not describe the behaviour of a particular future machine or process.
Which component references should appear in the 300kW enquiry?
Specify Cummins 6ZTAA13-G3 for the diesel engine, Stamford HCI444FS1 for the alternator and Deep Sea Electronics DSE7320 for the controller. Carry the same references into the technical offer, with any proposed substitution clearly identified for review.
